Can't zoom where I want in scene
OK now that it was confirmed to fix the problem I'll make it a response.

Blender zoom works in such a way that the more you zoom in, the less each scroll zooms in (still haven't found a better way to explain it). selecting the object you want to focus on and pressing "." on the numpad recenters the object in the view and resets the zoom so that it's much easier to navigate around your object.
